TTC on clomid

Alisha
I'm on my 3rd and last round of clomid right now. We have been TTC for a little over 3 yrs. I had a positive opk 3 days ago with brownish spotting...but then the next day had heavy CM..then last night had cramping on my right side. Felt more like pressure than cramping really. Now today...spotting pinkish blood? Never had this before. Been "doing the deed" pretty much every day (which is normal for us) called my fertility doctor today and she said they may have to change my treatment to another medication before trying <a href="https://glowing.com/glow-fertility-program">ivf</a>. Has anybody else had this problem? What could be happening? Somebody please respond ...I can't ever get anybody to answer anything I write on here lol pleeaase any advice!
